BER Building Energy Rating CERT Example

From the 1st of January 2009 a BER certificate is compulsory for all homes being sold or rented. If you are buying or renting a new house or apartment now, you are entitled to a BER - so do ask the seller/landlord or their agent for it.
All new homes (even when not for sale) must have a BER certificate before they are occupied as detailed under S.I. 666 under http://www.environ.ie/en/Legislation/DevelopmentandHousing/BuildingStand...
